Definitions

  • the invention relates to a sheet metal profile, preferably in a cold-rolled version, for creating support structures, stages and the like.
  • Cold rolled sheet metal profiles of this type are used in different heights, thicknesses and lengths primarily in the field of warehouse technology. Here they serve e.g. as a support beam for pallet racking systems. They are also used as main and secondary beams in the creation of intermediate stage constructions. In this case, a bar grid is first assembled from the sheet metal profiles in question, on which the stage plates are then placed. In this way, large stage constructions for storage purposes can be erected in a relatively short time.
  • the invention has for its object to provide a sheet metal profile for creating support structures, platforms and the like. With improved torsional behavior, which moreover enables a wider range of applications in practical use than the known sheet metal profiles.
  • a sheet metal profile of the type mentioned is proposed, with an overall cross-section inscribed in a rectangle with a height which clearly exceeds the width, with the narrow sides which delimit the top and bottom and which extend over its entire width and which have a multi-angled edge Web are connected to each other, the web, starting from two opposite edges of the narrow sides, initially extending a short distance along one broad side of the rectangle circumscribing the profile, the web then bends obliquely at an obtuse angle to the other broad side, where the web finally forms a flat middle piece arranged exactly in the plane of the other broad side.
  • the sheet profile also has the advantage of being particularly easy to connect to other structural parts, and in particular an identical, symmetrically positioned sheet profile. In practical use, the sheet profile is therefore available for a wide range of applications.
  • the sheet metal profile is shaped symmetrically with respect to the plane defined by half the height. In this way, the advantages of the sheet metal profile are achieved in any installation position.
  • connection with other structural parts and in particular with an identically designed and symmetrically attachable sheet profile is significantly improved if, according to a preferred embodiment of the invention, on those two opposite edges of the narrow sides from which the web does not extend, short anglings oriented at right angles to the narrow sides are molded on, which lie exactly in the plane of the center piece.
  • the sheet profile has a particularly favorable torsional behavior if the height-width ratio is between 2.5: 1 to 6: 1.
  • the ratio of the height of the profile to the height of the center piece is from 1.5: 1 to 2.5: 1.
  • the center piece has openings at regular intervals.
  • the weight of the sheet metal profile can be reduced considerably, so that it is also suitable for the production of lightweight structures.
  • the middle piece is above and below it Provide lines of symmetry with rows of holes. These rows of holes allow two identical sheet metal profiles of the type mentioned to be connected symmetrically to one another in order to obtain a high-strength beam in which the center of thrust and the line of action of the load lie exactly in the same plane. In this case, for optimal connection technology, it is advantageous if the distance between the top and bottom row of holes is 55 to 75% of the height of the center piece.
  • Fig. 1 shows a closed, symmetrical profile, as is known in various designs from the prior art.
  • the decisive advantage of such a profile is that the shear center SM of the profile is exactly on the line of action WL of a load acting perpendicular to the profile.
  • Such a profile is free of torsional moments. This applies in the same way to the profile, which also belongs to the prior art, in the form of a double T according to FIG. 2.
  • Fig. 6 shows that this profile is inscribed in a rectangle R, which has a significantly greater height than width.
  • the narrow sides of the rectangle R coincide with the upper narrow side 1 and the lower narrow side 2 of the profile.
  • Short bends 5, 6 are formed at right angles on two opposite edges 3, 4 of the narrow sides 1, 2. These bends 5, 6 are located in the plane of one of the broad sides of the rectangle R and are short compared to the height of the profile.
  • the edge 7, 8 respectively opposite the edges 3, 4 of the upper and lower narrow sides 1, 2 forms the transition to a connecting piece 9, 10, each of these connecting pieces 9, 10 being located in the plane of the rectangle R defined above.
  • the upper narrow side 1 and the lower narrow side 2 therefore merge into the angled portions 5 and 6 on one side, and into the connecting piece 9 and 10, which is also angled at right angles, on the other side.
  • the connecting pieces 9, 10 are part of a multi-angled web 11, which connects the upper narrow side 1 to the lower narrow side 2.
  • This web 11 includes inclined pieces 12, 13 which connect to the respective connecting piece 9, 10.
  • the transition between the connecting pieces 9, 10 and the respective inclined pieces 12, 13 is obtuse, as can be clearly seen in FIGS. 5 to 7.
  • the length of the inclined pieces 12, 13 is such that they extend to the opposite, broad side of the rectangle R, that is to say to the plane in which the bends 5, 6 are also located. There, the web 11 bends again at an obtuse angle, resulting in a longer, completely flat center piece 14.
  • Fig. 7 also shows that the connection of the two profiles via screw connections 15 in Area of the center pieces 14 is carried out.
  • FIGS. 5 and 6 show that the middle piece 14 has rows of holes 16 on both sides of the axis of symmetry S of the profile, which enable the screw connections 15 to be pushed through.
  • the distance between the upper and lower row of holes 16 is 55 to 75% of the height H of the middle piece 14.
  • the profile formed from a piece of sheet metal has a height-width ratio of approximately 4: 1 in the exemplary embodiment.
  • the ratio of the height of the profile to the height H of the middle piece 14 is approximately 1.85: 1.
  • the center piece 14 is provided with larger openings 17 at regular intervals.
  • FIG. 6 shows the position of the shear center SM in comparison to the line of action WL of the load in a sheet metal profile according to the invention. It can be seen that the special design of this sheet profile enables the center of thrust SM and the line of action WL to be brought close to one another, with it being an additional advantage that the center of thrust SM of this sheet profile lies approximately in the middle of the profile cross section.
